Geology of Tarrant County, Texas

The source geological map used is "Geologic Atlas of Texas,
Dallas Sheet" - Bureau of Economic Geology, 1987. The map
was digitally distorted in some spots to align the roads with the more
accurate modern map BUT there is still some distortions and alignment is
not perfect. Colors used here are arbitrary.
